Problem/Bug PlayerJoinEvent, Scanner, teleport

Hey Guys,
i have a Problem with the following code.

Code:

@EventHandler
    public void onJoin(PlayerJoinEvent e) throws FileNotFoundException{
        Location GelbSpa = new Location(world, 91, 29, -33);
        Scanner s;
       
            s = new Scanner(new File("C:/Users/Ole/Dropbox/Minecraft/Run's/Server-Running/Lobby/Gelb.txt"));
       
        ArrayList<String> Gelb = new ArrayList<String>();
        while (s.hasNext()){
            Gelb.add(s.next());
           
        }
        s.close();
        for(String str : Gelb){
        Player    p = Bukkit.getPlayer(str);
        p.teleport(GelbSpa);
            p.sendMessage("Du wurdest zu Gelb teleportiert!");
        }

The Server sends an error. I want to teleport all Players from Gelb.txt.

Thanks for all answers.
Ole

@bwfcwalshy

When i delet the last 5 lines, there is no error. So the fault is in the last 5 lines

Is there nobody who can help me? I changed the code a little bit.

Code:

@EventHandler
    public void onJoin(PlayerJoinEvent e) throws FileNotFoundException{
        Player p = e.getPlayer();
        Location GelbSpa = new Location(world, 91, 29, -33);
        Scanner s;
       
            s = new Scanner(new File("C:/Users/Ole/Dropbox/Minecraft/Run's/Server-Running/Lobby/Gelb.txt"));
       
        ArrayList<String> Gelb = new ArrayList<String>();
        while (s.hasNext()){
            Gelb.add(s.next());
           
        }
        s.close();
        if(Gelb.contains(p.getDisplayName())){
            gelb.addPlayer(p);
            p.teleport(GelbSpa);
           
        }

 

@0LUMIN4T0R, please, no scanner. Scanner is one of the most bugged classes Sun ever wrote. Use BufferedReader and see if the issue goes away.

 

I tried it, but i won't be teleportet. But it prints that it read the file.

Code:

    @EventHandler
    public void onJoin(PlayerJoinEvent e){
        Player p = e.getPlayer();
        world = p.getWorld();
        Location GelbSpa = new Location(world, 91, 29, -33);
        try{
         BufferedReader in = new BufferedReader(new FileReader(new File("C:/Users/Ole/Dropbox/Minecraft/Run's/Server-Running/Lobby/Gelb.txt")));
         System.out.println("Gelb.txt wurde erfolgreich geöffnet!");
         ArrayList<String> Gelb = new ArrayList<String>();
         int line = 0;
         for (String x = in.readLine(); x != null; x = in.readLine())
         {
          

             line++;
             Gelb.add(x);
          
         }
         
     
     
        if(Gelb.contains(p.getPlayer().getDisplayName())){
            gelb.addPlayer(p);
            p.teleport(GelbSpa);
         
        }
        }
        catch(IOException er){
            System.out.println("Gelb.txt konnte nicht ausgelesen werden!");
        }
